Native vs. Non-native ‘th‘. A short comparison By Finn Kristensen Sabrina Riedel Tim Rocktaeschel Marco Tiedemann. Hypothesis.

German English speakers substitute the sound /z/ for the sounds /θ/ and /ð/ because these sounds don’t exist in the German language, and are therefore difficult to reproduce.
